Abstract

An alternating-current permanent magnet drainage pump includes a pump cover, a pump body, a magnetic core, a rotating shaft, a stator core and coils. The coils are wound around a coil former, and the stator core is assembled to the coils. The pump body is a shell formed by surrounding a contour of the coils, the coil former, and the stator core which have been assembled to perform an integrated injection molding. The shell defines a magnetic core accommodating space used for accommodating the magnetic core and having an opening at a top portion. The magnetic core accommodating space extends from the opening to a center of the pump body. A supporting member is arranged in the opening at the top portion of the magnetic core accommodating space for supporting a bearing of the rotating shaft.

Abstract

A method for emptying the rectum by using an electronic sanitary appliance arranged on a toilet, comprises: extending out a rectum flushing nozzle so that it locates underneath of the anus of a user who is seated on the toilet; spraying a first linear water flow to the anus from the rectum flushing nozzle, modifying the relative position between the rectum flushing nozzle and the user's anus so that the first linear water flow aims at the anus; spraying the anus with a second linear water flow from the rectum flushing nozzle to pass through the anus and into the rectum; spraying continuously the second linear water flow and stopping spray of the second linear water flow when the user has a desire to defecate, then the user discharges the substance in the rectum.

Abstract

A permanent-magnet synchronous motor of a draining pump is disclosed. It includes a permanent-magnet rotor for driving an impeller to rotate, a pump body for supporting the permanent-magnet rotor, a stator core and a stator coil. Among which, the stator coil is constructed with an enamelled aluminum wire winding which is coiled by an enamelled aluminum wire and sealed in a container. The invention applies the enamelled aluminum wire to the permanent-magnet synchronous motor of a draining pump. The winding of the stator coil and a welding part of its lead-out wire are sealed with plastic or epoxy resin which effectively isolate them from outside air, especially damp air. Therefore, the invention prevent the enamelled aluminum wire winding of the stator coil and the welding part of its lead-out wire from being oxidized in air and being corroded by the moisture, acid or alkaline matter in damp air.
